Eraser holder



lNvENToR I ATTOR N EYS Jan. 2, 1934. F. M. HALE ERASER HOLDER Filed May 3, 1935 Patented Jan. 2, 1934 UNITED STATES PATENT oir-Fics 11 Claims.

This invention relates to eraser holders, and its general object is to provide a reiillable holder for erasers, that can be attached to or be included as a part of writing implements such as pens and pencils, or the holdercan be a distinct and separate unit, but in any event is adapted to receive and house an eraser or erasers to retain the same in a clean and flexible condition and which can be fed therefrom to provide an extending portion for use, until completely consumed.

Another object of the invention is to provide an eraser holder that is capable of receiving a relatively large quantity of erasing material, for use in an easy and convenient manner and so as to last for a prolonged period of time.

Another object of the invention is to provide an eraser holder of the character set forth, that is simple in construction, easy to actuate, inexpensive to manufacture, and extremely eflicient in use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a perspective view showing one form of my holder as being a part of a mechanical pencil.

Figure 2 is a similar view of the parts of the form shown in Figure 1 separated.

Figure 3 is a perspective view showing another form for use with the usual wood lead pencil.

Figure 4 is a longitudinal sectional view taken through the form shown in Figure 3.

Figure 5 is a perspective view of another modi- Ified form for use distinct and separate from a writing implement.

Figure 6 is a longitudinal sectional view taken through the form shown in Figure 5.

Figure 7 is a perspective view of a further modified form of the type as shown in Figures 5 and 6.

Figure 8 is a similar view of the parts of the form shown in Figure '7, separated.

Referring to the drawing in detail, and particularly to Figures 1 and 2 which discloses one form of my invention that is included as a part of a mechanical pencil, the body of which is indicated by the reference numeral 1, and has secured thereto and rising from its upper end a reduced portion providing a threaded boss 2.

Formed with or otherwise secured to the threaded boss 2 and rising centrally therefrom is a relatively long stem 3 which may be threaded as shown, but in any event is serrated, rough- (Cl. 1Z0-36) ened or provided with teeth for the purpose of holding a cylindrical eraser 4 thereon and which is provided with a longitudinally centrally arranged bore 5 to receive the stem 3. The eraser 4 may be formed from any well known erasing material and is initially longer than the stem k3.v

Surrounding the eraser 4 and threadedly secured to the boss 2 is a tubular sleeve 6 which cooperates with the stem 3 in holding the eraser in relatively i'lXed position for use as shown in Figure 1. y

In Figures 3 and 4 I have illustrated a modifiedi form of my invention for u se on the sual wood lead pencil and which includes a longitudinally split barrel portion 7 having formed with or otherwise secured to its upper end a threaded boss 8 that has a stem 9 similar to the stem 3 secured thereto and rising centrally therefrom as clearly shown in Figure 4. The stem 9 is adapted to receive a cylindrical eraser 10 that is provided with a longitudinally arranged centrally disposed bore for that purpose, while sur-v rounding the eraser 10 is a tubular sleeve 11 which is threadedly secured to the boss 8.

It will be noted from Figure 3 that the pencil 12 is adapted to receive the barrel portion 7 in the customary manner and of course the barrel portion 7 is split so that it will set up a resilient action to grip the pencil as will be apparent.

While I have illustrated and so far described my eraser holder as being associated with pencils, I want it understood that it can be associated with any type of writing implements including fountain pens and the like, or the holder can be a distinct and separate unit having no connectionV with a writing implement such as the modied form illustrated in Figures 5 and 6. In that form I provide a cylindrical body member 13 that is threaded and has formed therewith midway its ends an annular flange 14, the opposite sides of which provide shoulders to receive tubular sleeves 15 that are threadedly secured to the body 13.

as clearly shown in Figure 6.

Extending from opposite ends of the cylindrical body 13 are stems 16 which are threaded as shown, or serrated or otherwise roughened to hold cylindrical erasers 17 which are provided with centrally arranged longitudinally disposed bores for the passage of the stems therein. The sleeves 15 surround the erasers 1'7 and cooperate f inner ends of rectangular housing members 20 that are slidably associated with the body 18 as shown in Figure 7 and suggested in Figure 8.

Secured to and extending from the opposite sides of the body 18 and centrallytherefrom are stems 21 which are likewise threaded in the form as shown to hold erasers 22 thereon, and the erasers are received in the housing members which are shaped to fit the same as Well as the body 18 as Will be apparent. The stems 21, as well as the stems 3, 9 and 16 may bel solid, .or tubular, as preferred. From the above description and disclosure of the drawing, it Will be obvious that I have provided an eraser holder that is capable of being associated with Writing implements or can -be a distinct and separate unit, 'and is 'capable 'of receiving a large quantity of erasing material that can be fed' therefrom by being moved outwardly on its stem which is roughened so as to cooperate with the housing in holding the material in xed relation with a 'portion disposed for use and until the material is entirely con'- sumed. The housing members which `not 'onlyI include the members 20 but also ther 'tubular sleeves retain the erasing material in a clean and flexible condition and these members can `be/readily removed so as to facilitate the outward'movement of the erasing material, as 'Well `as 'when refilling the holders when the erasing material.

is entirely consumed. l

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that 4I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claims. f
